Childhood

Childhood is an achievement in GRIS.

Appearance
It appears to be an explosion.

Achieving
The player can get this achievement by collecting all of the mementos.

Players will be able to access this area by entering Chapter 5 and heading to the left and falling below where Gris appears.

Down there is an entrance that is hidden as players fall down the hole, meaning players must try to aim towards the right side, in the broken wall.

Players must sing in this area to access the final cutscene.
